Ölkofra þáttr
Ölkofra þáttr, the "Tale of Ölkofri" or the "Tale of Ale-Hood", is a þáttr, a minor Old Norse prose genre related to the sagas of Icelanders. Preserved in the 14th-century manuscript known as Möðruvallabók, the tale is a satire on the judicial system of the medieval Icelandic Commonwealth. It tells the story of an ale-brewer, named Þórhallr but known as Ölkofri or "Ale-Hood" for the hood that he habitually wears. Ölkofri accidentally sets fire to some valuable woodland belonging to six powerful Icelandic chieftains. These chieftains consequently file suit against him at the Althing in an effort to get him outlawed, but thanks to the efforts of men who unexpectedly come to his aid, Ölkofri manages to escape this fate.
On a side note, the main character's occupation -- brewer and seller of ale at the Icelandic Alþing -- provides some confirmation that barley was once grown in Iceland during the tail end of a warm phase known as the Medieval Warm Period. Grain could not be cultivated there as the climate cooled and growing seasons shrank.
